The present application is a national phase application under 35 U.S.C. § 371 of International Application No. PCT/CN2015/088570 filed Aug. 31, 2015, which claims priority to Chinese patent application No. 201410453791.3, entitled “Method and System for improving security of a mobile terminal” filed Sep. 5, 2014. The entire contents of each of the above-referenced applications are incorporated into the present application by reference.

TECHNICAL FIELD

The present application relates to the field of mobile terminal security technology, particularly to a method and system for improving the security of a mobile terminal.

BACKGROUND

With the development of technology, mobile phones, tablets and other mobile terminals gradually enter into people's life. For the purpose of anti-theft, some verification modes, such as a combination lock, are often used by a user to improve the security of a mobile terminal.

Existing verification modes for improving the security of a mobile terminal are active verifications, in which the mobile terminal reminds the user to perform verification via an interface for inputting verification information. The user inputs the verification information, and the user can perform various operations on the mobile terminal after the verification is passed. The active verification modes, however, need to remind a user to perform verification, and when a thief finds that a mobile phone needs to be verified, he or she will not perform the verification, which causes failure of the verification and it cannot be known whether the current user is the owner of the mobile phone, thus also incapable of performing other security processing such as alarming or the like.

DETAILED DESCRIPTION OF THE INVENTION

Next, clear and complete description of the technical solution of the present application will be given in combination of drawings of the present application. Obviously, the embodiments described is merely parts of the embodiments of the present application, instead of all the embodiments. Depending on the embodiments of the present application, all other embodiments obtained by those of ordinary skilled in the art without any creative efforts belong to the protection scope of the present application.

As shown in FIG. 1, a method for improving security of a mobile terminal provided by embodiments of the present application may comprise:

S100, when the mobile terminal is in a locked state, obtaining a slide-to-unlock operation of a current user;

Specifically, since there are various slide-to-unlock manners, there are various different slide-to-unlock operation forms, for example: sliding from left to right, sliding from the bottom up etc. The slide-to-unlock operation obtained in S100 may be the starting point, the ending point, the track, the speed, the length, the direction and the like of the slide-to-unlock operation.

S200, determining whether the slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner of the mobile terminal, if yes, performing S300, otherwise performing S400;

Here, the prerecorded slide-to-unlock operation habits of the owner may include any one or more of: the range of a habitual starting point of the slide-to-unlock operation of the owner, the range of a habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, a habitual direction of the slide-to-unlock operation of the owner, a habitual speed of the slide-to-unlock operation of the owner, and a habitual track of the slide-to-unlock operation of the owner. Optionally, the slide-to-unlock operation habits of the owner can be collected beforehand, which requires the owner to perform slide-to-unlock operations for a plurality of times so as to record the slide-to-unlock operations and determine the slide-to-unlock operation habits of the owner according to the slide-to-unlock operations of the owner. For example: the owner inputs slide-to-unlock operations for ten times, whose lengths respectively are: 3.0 cm, 2.8 cm, 4.1 cm, 2.7 cm, 5.7 cm, 3.6 cm, 3.1 cm, 3.8 cm, 3.7 cm, 4.2 cm. Since 5.7 cm is the longest and has a huge difference with the second longest length 4.2 cm, 5.7 cm can be abandoned, and the range of the habitual length of the slide-to-unlock operation of the owner is from 2.7 cm to 4.2 cm. Of course, the owner can modify the prerecorded slide-to-unlock operation habits of the owner to improve the accuracy of verification.

It can be understood that, due to the differences of the hand size, the finger length, the agility and personal habits, the slide-to-unlock operation habits are different when the slide-to-unlock operations is performed by different people. Therefore, whether the current user is the owner can be determined according to the prerecorded slide-to-unlock operation habits of the owner and subsequent security processing can be performed.

There are various specific ways to determine whether the slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner, such as: determining all or part of parameters of the prerecorded slide-to-unlock operation habits of the owner. The prerecorded slide-to-unlock operation habits are assumed to include: the range of a habitual starting point of the slide-to-unlock operation of the owner, the range of an habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, a habitual direction of the slide-to-unlock operation of the owner, a habitual speed of the slide-to-unlock operation of the owner, and a habitual track of the slide-to-unlock operation of the owner. In this case, it is possible to only determine whether the slide-to-unlock operation of the current user matches with the habitual track of the slide-to-unlock operation of the owner, and execute S300 when it does, otherwise, execute S400. Of course, it is also possible to only determine whether the slide-to-unlock operation of the current user matches with the range of the habitual starting point of the slide-to-unlock operation of the owner and the habitual track of the slide-to-unlock operation of the owner, and execute S300 when it matches with both, otherwise execute S400. Of course, it is also possible to determine whether the slide-to-unlock operation of the current user matches with the range of the habitual starting point of the slide-to-unlock operation of the owner, the range of the habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, the habitual direction of the slide-to-unlock operation of the owner, the habitual speed of the slide-to-unlock operation of the owner and the habitual track of the slide-to-unlock operation of the owner, and execute S300 when it matches with all of these, otherwise, execute S400.

S300, performing unlocking processing which puts the mobile terminal in an unlocked state;

S400, performing first security processing which is different from the unlocking processing.

Here, the first security processing may be: maintaining the locked state of the mobile terminal, and performing second security processing.

Thus, when the slide-to-unlock operation of the current user does not match with the slide-to-unlock operation habits of the owner, the slide-to-unlock operation of this user cannot slide to unlock the mobile terminal, so that the current user cannot use the mobile terminal, and thus the security of the mobile terminal is ensured effectively.

It can be understood that, when the current user perceives that he/she is found not to be the owner by the mobile terminal, the current user will perform some operations (such as shutting down the mobile terminal or pulling out the buttery) to prevent possible security processing such as alarming and the like made by the mobile terminal. Therefore, in other embodiments of the present application, the first security processing may also be: performing unlocking processing which puts the mobile terminal in an unlocked state and performing second security processing.

In this case, the mobile terminal still executes the unlocking processing, such that the current user cannot perceive that he/she has been found not to be the owner. In this way, the mobile terminal can perform security processing without being interrupted by the current user.

Of course, in other embodiments of the present application, the first security processing in S400 may include:

displaying an interface for inputting verification information, and receiving the verification information input by a current user;

determining whether the verification information input by the current user is identical with preset verification information, if yes, performing unlocking processing, otherwise performing second security processing.

In some cases, the slide-to-unlock operation of the owner may not match with his/her own operation habit. In this case, in order to prevent an incorrect operation, the user can be reminded to perform verification in other ways such as password etc.

Optionally, the above-mentioned second security processing in the embodiments of the present application may comprise any one or more of the following seven processing:

the first processing, obtaining first information and sending it to an external device. The first information includes any one or more of: a geographical location of the mobile terminal, images taken by the mobile terminal, videos filmed by the mobile terminal, audios recorded by the mobile terminal, and fingerprints collected by the mobile terminal;

the second processing, locking all or part of functions of each application program in a preset application program group, such that the current user cannot use the locked functions;

the third processing, restoring to factory settings;

the forth processing, clearing sensitive data;

the fifth processing, sending sensitive data to an external device;

the sixth processing, playing a preset audio;

the seventh processing, sending a notification that the mobile terminal is stolen to an external device.

In the above-mentioned first processing, the images taken by the mobile terminal, the videos filmed by the mobile terminal, the audios recorded by the mobile terminal and the fingerprints collected by the mobile terminal can be those obtained after the current user's information is collected, for example, the head image of the current user collected by a front-facing camera. In the first processing, information of the current user and/or the geographic location of the mobile terminal can be sent to an external device, thus providing important information for the owner of the mobile terminal to take back the mobile terminal. Wherein, the external device to which the first information is sent can be preset, for example, as the device providing security service by the manufacturer of the mobile terminal or a friend's mobile device etc.

In the above-mentioned second processing, functions of application programs in the mobile terminal can be locked, and thus the use of the mobile terminal by the current user can be restrained. The owner of the mobile terminal can put a sensitive application program into a preset application program group beforehand, and the sensitive application program may be an application program containing the owner's personal information or the information of the contacts of the owner, such as messages, contact list, instant messaging software etc. Of course, for some applications, it is possible to lock only part of their functions. For example, a camera application program has the functions of photographing, video-filming and photo/video viewing, and in the present application, it is possible to only lock the function of photo/video viewing and not to lock the functions of photographing and video-filming. In this way, photographing and video-filming can be executed by the camera application program.

Since there may be a large amount of sensitive information (such as account passwords), sensitive files, important application programs installed by a user, the above-mentioned third processing can be performed after the mobile terminal is stolen, i.e. restoring to factory settings. In this way, the sensitive information, sensitive files, important application programs installed by the user can all be cleared. Of course, the forth processing of clearing only the sensitive information can also be performed. In other embodiments of the present application, the fifth processing of sending the sensitive data to an external device can also be performed. In this way, the owner will not lose sensitive information because the mobile terminal is stolen.

After the mobile terminal is stolen, the sixth processing of playing an alarming audio to alarm surrounding people and to stop the behavior of the current user can be performed.

In the seventh processing, the notification that the mobile terminal is stolen can be sent to an external device to alert related persons.

Optionally, in embodiments of the present application, the mobile terminal can be recognized by other devices through International Mobile Equipment Identity (IMEI) of said mobile terminal so as to communicate with the mobile terminal.

A person, who is not the owner, may perform the processing of refurbishment, changing phone number etc, after obtaining the mobile terminal. However, the IMEI is unique, invariable for each mobile terminal, Therefore, the communication with the mobile terminal can be remained according to the IMEI.

The method for improving security of a mobile terminal provided by embodiments of the present application can be used to determine whether the obtained slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner, thereby determine whether the current user is the owner, and perform corresponding processing. In the present application, it is not required to remind a user to input verification information, such that the current user cannot perceive that verification is currently in process, and thereby the validity of the verification can be ensured. With the present application, the security of the mobile terminal can be improved effectively.

As shown in FIG. 2, another method for improving security of a mobile terminal provided by embodiments of the present application may further include:

S500, obtaining a screen switching operation of the current user when the mobile terminal is in an unlocked state;

S600, determining whether the screen switching operation matches with prerecorded screen switching operation habits of the owner, if not, performing S700; if yes, terminating the processing.

In other embodiments of the present application, when the screen switching operation matches with the screen switching operation habits of the owner, it is also possible to perform the screen switching operation.

S700, performing second security processing.

The second security processing performed in S700 has been described in the previous embodiments, which will not be described here repeatedly.

In the embodiment shown in FIG. 2, S500 is performed after S300, while in other embodiments of the present application, S500 may also be performed after S400. When the current user is not the owner, the slide-to-unlock operation of the current user may also match with prerecorded slide-to-unlock operation habits of the owner. In order to further improve the security of the mobile terminal, it is also possible to verify a user's screen switching operation in the embodiment shown in FIG. 2. Thus, verification can be performed without being perceived by the current user, and the security of a mobile terminal is further improved.

Corresponding to the method, the present application further provides a system for improving security of a mobile terminal.

As shown in FIG. 3, the system for improving security of a mobile terminal provided by embodiments of the present application may comprise: a slide-to-unlock operation obtaining unit 100, a slide-to-unlock habit determining unit 200, an unlocking unit 300 and a first security processing unit 400, wherein

the slide-to-unlock operation obtaining unit 100 is used to obtain a slide-to-unlock operation of a current user when the mobile terminal is in a locked state;

the slide-to-unlock operation obtained by the slide-to-unlock operation obtaining unit 100 may be the starting point, the ending point, the track, the speed, the length, the direction and the like of the slide-to-unlock operation.

The slide-to-unlock habit determining unit 200 is used to determine whether the slide-to-unlock matches with prerecorded slide-to-unlock operation habits of an owner of the mobile terminal, if yes, trigger the unlocking unit 300, otherwise trigger the first security processing unit 400;

wherein, the prerecorded slide-to-unlock operation habits of the owner may include any one or more of: the range of a habitual starting point of the slide-to-unlock operation of the owner, the range of an habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, a habitual direction of the slide-to-unlock operation of the owner, a habitual speed of the slide-to-unlock operation of the owner, and a habitual track of the slide-to-unlock operation of the owner. Optionally, the slide-to-unlock operation habits of the owner can be collected beforehand, which requires the owner to perform slide-to-unlock operations for a plurality of times so as to record the slide-to-unlock operations and determine the slide-to-unlock operation habits of the owner according to the slide-to-unlock operations of the owner.

It can be understood that, due to the differences of the hand size, the finger length, the agility and personal habits, the slide-to-unlock operation habits are different when the slide-to-unlock operations is performed by different people. Therefore, whether the current user is the owner can be determined according to the prerecorded slide-to-unlock operation habits of the owner and subsequent security processing can be performed.

There are various specific ways to determine whether the slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner, such as: determining all or part of parameters of the prerecorded slide-to-unlock operation habits of the owner. The prerecorded slide-to-unlock operation habits are assumed to include: the range of a habitual starting point of the slide-to-unlock operation of the owner, the range of an habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, a habitual direction of the slide-to-unlock operation of the owner, a habitual speed of the slide-to-unlock operation of the owner, and a habitual track of the slide-to-unlock operation of the owner. In this case, it is possible to only determine whether the slide-to-unlock operation of the current user matches with the habitual track of the slide-to-unlock operation of the owner, and trigger the unlocking unit 300 when it is, otherwise, trigger the first security processing unit 400. Of course, it is also possible to only determine whether the slide-to-unlock operation of the current user matches with the range of the habitual starting point of the slide-to-unlock operation of the owner and the habitual track of the slide-to-unlock operation of the owner, and trigger the unlocking unit 300 when it matches with both, otherwise trigger the first security processing unit 400. Of course, it is also possible to determine whether the slide-to-unlock operation of the current user matches with the range of the habitual starting point of the slide-to-unlock operation of the owner, the range of the habitual ending point of the slide-to-unlock operation of the owner, the range of the habitual length of the slide-to-unlock operation of the owner, the habitual direction of the slide-to-unlock operation of the owner, the habitual speed of the slide-to-unlock operation of the owner and the habitual track of the slide-to-unlock operation of the owner, and trigger the unlocking unit 300 when it matches with all of these, otherwise, trigger the first security processing unit 400.

The unlocking unit 300 is used to perform unlocking processing, which puts the mobile terminal in an unlocked state;

the first security processing unit 400 is used to perform the first security processing, which is different from the unlocking processing.

Optionally, the first security processing unit 400 may comprise: a locking maintaining unit and a second security processing unit, wherein

the locking maintaining unit is used to maintain the locked state of the mobile terminal;

the second security processing unit is used to perform second security processing.

Thus, when the slide-to-unlock operation of the current user does not match with the slide-to-unlock operation habits of the owner, the slide-to-unlock operation of this user cannot slide to unlock the mobile terminal, so that the current user cannot use the mobile terminal, and thus the security of the mobile terminal is ensured effectively.
